Vault Strict Typing cleanup (#12512)

* remove strict types from `NewDeviceVerificationNotice`
- Add null default value for class properties
- Enforce that the userId is passed
- noticeState$ can return null

* remove strict types from `CopyCipherFieldService`
- refactor title to be a string rather than null

* remove strict types from `PasswordRepromptComponent`
- add guard to exit early on submit but also solves removing null/undefined from typing

* use bang to ensure required input

* remove strict types from `CopyCipherFieldDirective`
- add bang for required types
- add default values for null types

* add bang for constant variables in cipher form stories

* remove strict types from `DeleteAttachmentComponent`
